The principle of traction is used in plastic surgeries for tissue expansion. The regeneration of new tissue is used to cover cutaneous defects, burns, and hair loss areas. It is also used in orthopaedic surgeries to enlarge the diaphysis of bones and phalanges. Andropenis ® is based on the principle of traction.
